'TYPE-CASTING MAoHlNE.

SPECIFIGATION forming part of Letters Patent No. 544,317, dated August13, 1895. Application filed August 31, 1894. Serial No. 521,815. (Nomodel.)

To all whom it may concern:

Be it known that I, WALTER S. MARDER, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Type-Casting Machines, of which thefollowing is a full, clear, and exact specilication.

My invention relates more particularly to the mold of a typecastingmachine, and `the improvements have especial reference to means forcasting what is known in the art as compositors slugs.

The primary object of my invention is to provide means whereby theseslugsmay be cast at one operation, as readily and accurately as theordinary type are now cast, from any desired number of matrices.

With these ends in view my invention con- Sists in certain features ofnovelty in the construction, combination, and arrangement of parts bywhich the said objects and certain other objects hereinafter disclosedare attained, all as fully explained with reference to the accompanyingdrawings, and more particularly pointed out in the claims.

In the said drawings, Figure lis a perspective view ofthe twomold-sections, showin g my improvements in connection therewith. Figs. 2and 8 are, respectively, the lower and upper sections of the mold shownseparated. Fig. 4 is an inner or face view of my improved box forholding the matrices, as hereinafter described, shown in perspective.Fig. 5 is an end perspective View of said box, showing two matricestherein. Fig. 6 is a similar view showing one matrix and two blankssecured in the box. Fig. 7 is a perspective view of the slugs cast by myimprovements. Fig. 8 is a perspective view ot' a mold-block and mold,showing my improvements in connection therewith and in position forcasting; and Fig. 9 is a detail vertical section taken transversely-ofthe mold, showing the mold filled.

Like Signs of reference indicate like parts throughout the severalviews.

In carrying out my invention I employ a box for the reception of thematrix or matrices, and which box holds such matrix or matrices in themold or in contact with the .of the slug on either side of thecharacter.

Referring to the drawings, l and 2 repre sent, respectively, the upperand lower sections of the mold,fthe former of which sections is providedwith the usual register-block 3 and stool-piece 4, While the other isprovided with a similar registerblock 3a. The mold thus constituted maybe of the usual or any suitable form, with the exception that thestool-piece 4t is considerably elongated as a consequence of employingthe wide box for the matrices which the stool-piece holds in place, ashereinafter described. I

My improved box for the reception of the matrix or matrices is moreclearly shown in Figs. 4 to 6, inclusive, and it preferably consists ofva back plate 5 and two side pieces or blocks 6, which are rigidlysecured to the inner face of the plate 5 with a space 7 between them bymeans of screws 8 or other suitable devices, the upper ends of theblocks 6 being connected together by an end piece 9, secured thereto bymeans of screws 10, and thus constituting with the pieces 5 6 the boxfor the reception of the matrices ll, which are placed between theblocks 6, in the manner shown in Fig. 5, and securely held in positionagainst the end plate 9, which constitutes a gage for determining thelocation of the characters l2 ofthe matrices. The matrices may beclamped in position by any suitable means, but I preferably provide oneof the blocks 6 in the side, as shown in Figs. 5 and 6, with a pair ofsetscrews 13, whose heads are countersunk, so as to be out ot' the wayof the registerblocks 3, while their inner ends are adapted to protrudethrough the bores 14 .in the block 6 and impinge the adjacent matrix.

' When it is desired to cast a slug from a sin- ICO y gle matrix of lesswidth than the space 7 between the blocks 6 the surplus space may befilled by means of blanks 15, as shown in Fig. 6.

The faces of the blocks 6 are dressed, and the sum of their width incross section added to the width of the space 7 is equal to the lengthof the body of the slug shown in Fig. 7.

In inserting my improved matrix-box in the machine the upper section 1ot' the mold is elevated in the usual manner, and the box is theninserted between the lower section and the end of the usualmatrix-spring 16, so as to rest against the register-block 3a. The uppersection of the mold is then lowered and the stool 4 rested upon theupper edge of the box, while the other register-block 3 comes againstthe side edge in the manner shown in Fig. 1, the faces of the blocks 6resting snugly against the faces of the mold-sections, whereby theinterior of the mold comprised by the two mold-sections, the matrix, andthe blocks 6 will consist of an elongated cavity having the intaglio 12at its mid-length or at any other desired point in its length. The backof the plate 5 of the box is provided with a socket or cavity 17 for thereception of the pointed end of the matrixspring 16, which latter isprovided with the usual lug or finger 18, against which bears the end ofthe matrixspring lever 19 for holding the matrix-box firmly in position.At the conclusion of the casting operation the upper end of thematrixbox is thrown outward after the manner of manipulating an ordinarymatrix by means ot' the matrix-lever 20, which bears against the loweredge of the plate 5, as shown in Fig. S, and to the end that the loweredge of the matrix-box may be carried farther inward the lower ends ofthe blocks 6 are beveled at 2l, as shown in Figs. 5 and 6.

The outer edges of the blocks 6 are provided with plates 22, securedthereto in any suitable way, which. come against the register-blocks 3 3and hold the edges of the blocks 6 away from the latter, the edges ofthe plates 22 being arranged slightly below the faces of the blocks 6,so as to avoid contact with the faces of the mold-sections.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. In a type casting machine, the combination with a mold, of a box forthe reception of the matrix, said box being independent of the matrixand having dressed faces adapted to tit against the face of the mold,and means for pressing said box against the mold, substantially as setforth.

2. In a type casting machine, the combination with mold sections havingregister blocks and a stool-piece, of a box for receiving and holding amatrix, adapted to tit between said blocks and stool and having thebroadened faces adapted to fit against the mold sections, and means forholding said box in place, substantially as set forth.

3. In a type casting machine, the combination with the mold sectionshaving register blocks and a stool-piece, of a box for receiving andholding a matrix, adapted to fit between said blocks and stool pieceand. having broadened faces adapted to fit against the mold sections,set screws arranged in the side of said box and adapted to impinge thematrix, and means for holding said box in place, substantially as setforth.

4. In a type casting machine, the combination with a mold havingregister blocks, of a box for receiving and holdinga matrix, adapted tofit between said register blocks, set screws countersunk in the side ofsaid box and adapted to impinge said matrix, and means for holding saidbox in place, substantially as set forth.

5. In a type casting machine the combination with a mold, of a box forreceiving and holding a matrix, consisting of a plate, two blockssecured to said plate with a space between them and having broad dressedouter surfaces adapted to lit against the mold, the gage bar 9 securedacross the ends of said blocks, set screws passing through one of saidblocks and adapted to impinge the matrix, and means for holding saidmatrix box in place, substantially as set forth.

6. As a new and useful article of manufacture, a matrix box providedwith the blocks 6 secured together and having their ends beveled, andsaid box being provided with a space between said blocks 6, forreceiving and removably holding a matrix, substantially as set forth.

7. In a type casting machine, the combination with the mold havingregister' blocks, of a matrix box having the blocks 6 provided withdressed surfaces adapted to fit against the mold, and the plates 22secured to the blocks 6 and adapted to come against the said registerblocks, substantially as set forth.

8. In a type casting machine the combination with the mold block andmold provided with a matrix spring, of a box for receiving and removablyholding the matrix, adapted to fit against the mold and being providedin its outer side with a socket for the reception of the end of the saidmatrix spring, substantially as set forth.
